As a continuation of a long-term observational program with the purpose
of deriving the chemical abundances of southern planetary nebulae (PN),
we present here the line fluxes, colour excesses, electron temperatures and
densities, and abundances of He, O, N, S, Ar and Ne for 15 PN. These objects
were classified according to the Peimbert classification scheme, taking
into account the chemical and kinematical properties as well as
distance-independent correlations.

Key words: planetary nebulae: general / ISM: abundances
